Description

【０００１】
【発明の属する技術分野】
本発明は、主として血液透析時に使用される翼状針のチューブ上に配置され使用されるクランプに関する。
【０００２】
【従来の技術】
医療用穿刺針の使用後には刃先保護のためにリキャップが行われる。この操作時に、医療従事者が誤って指先を損傷し、エイズや肝炎等に感染してしまうという事故が問題となっている。この問題に対しては種々の対策がなされており、例えば翼状針についても、チューブ上にスライド可能にプロテクターを配置したり（特許第２６７３６８２号公報参照）、針管支持部とプロテクターを屈曲可能な連結部で連結し、使用後にこの連結部を屈曲させてプロテクターを針管に被せる（特許第２８１３８８６号公報参照）等の技術が知られている。
一方、血液透析で使用される翼状針においては、血液回路接続時等の血液噴出を防ぐために、チューブ内流路を一時的に遮断するクランプがチューブ上に配置されている。
従って、血液透析で使用される翼状針においては、誤穿刺防止対策と血液噴出防止対策のためにプロテクターとクランプの二部材が必要であり、このことはコストアップにつながるとともに、医療従事者にとっても操作が煩雑であるという欠点を有していた。
【０００３】
【発明が解決しようとする課題】
本発明は、上記の問題を解決するためのもので、プロテクターの機能とクランプの機能を兼ね備えた部材、すなわち、リキャップ操作を必要としない翼状針用クランプを提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明者は上記目的を達成するために鋭意検討の結果、クランプの上部材または下部材に針及びハブを収容可能な空間を設け、使用後にこの空間に針及びハブを導入できるようにすることにより、プロテクター機能を備えた翼状針用クランプが得られることを見出し、本発明に到達した。
【０００５】
すなわち本発明は、チューブ挿通孔を有する基端側の可撓性湾曲部と、該湾曲部を介して接続された上部材及び下部材を含み、該上部材と下部材が先端側で係脱自在に係合可能であり、上部材と下部材が係合した時にチューブが圧迫されるようにされてなる翼状針用クランプであって、非係合時に上部材と下部材の間に少なくとも翼を導入可能な間隙が生じるようにされるとともに、上部材または下部材に針及びハブを収容可能な空間が設けられたことを特徴とする翼状針用クランプである。
ここで、上部材に左右一対の係合フックが設けられるとともに、下部材に前記係合フックと係合する被係合部が設けられているのが好ましい。
【０００６】
【発明の実施の形態】
本発明の実施例を図面に基づいて説明する。
図１は本発明の一実施例を示す斜視図である。本発明の翼状針用クランプは、チューブ挿通孔１１を有する基端側の可撓性湾曲部１と、湾曲部１を介して接続された上部材２及び下部材３を含んでおり、上部材２と下部材３は先端側で係脱自在に係合可能になっている。そして、上部材２と下部材３が係合したときにチューブが圧迫されるようになっており、非係合時には上部材２と下部材３の間に少なくとも翼を導入可能な間隙が生じるようになっている。また、上部材２または下部材３には針及びハブを収容可能な空間が設けられている。
【０００７】
湾曲部１は、上部材２及び下部材３を接続する可撓性の部材であり、本例において、これら湾曲部１、上部材２、下部材３は、ポリスチレン、ポリカーボネート、ポリプロピレン、ポリエチレン等からなる合成樹脂で一体に形成されている。また、湾曲部１はチューブ挿通孔１１を有しており、このチューブ挿通孔１１にチューブが挿通された状態で、本発明の翼状針用クランプは使用される。尚、湾曲の度合いについて、本例では上部材２と下部材３がほぼ平行になる程度に湾曲されているが、これらの部材により形成される角度は３０度位になるまで大きくしてもよい。
【０００８】
上部材２には、先端側に左右一対の係合フック２１が設けられ、この係合フック２１より基端側にはチューブ圧迫のための押圧部２２が、さらに基端側には収容されたハブを固定するためのハブ固定手段２３が設けられている。
左右一対の係合フック２１は、これらの間にチューブを挿通できるようにチューブ外径よりも広い間隔をおいて設けられ、後述する下部材３の被係合部３１と係合するよう鉤状に形成されている。そして、係合フック２１と被係合部３１の非係合時には、これらの間に少なくとも翼を導入可能な間隙が生じるようになっている。また、係合フック２１は先端側から基端側に向かって傾斜しており、本例のように係合フック２１と被係合部３１の間に生じる間隙が狭い場合であっても、翼状針の翼が導入しやすいようになっている。尚、係合フック２１と被係合部３１の係合状態の解除操作をしやすくするために、係合フック２１に把持部２４を設けてもよい。
押圧部２２は、係合フック２１と被係合部３１の係合時にチューブを圧迫するためのものであり、左右に延びる縦断面山形形状を有している。この形状については、チューブを圧迫できる形状であれば特に限定されない。尚、係合フック２１と被係合部３１の非係合時にチューブを圧迫しないような構造であれば、係合フック２１を下部材３に設け、押圧部２２を下部材３に設けるようにしてもよい。
ハブ固定手段２３は、後述する下部材３の収容空間３２に針及びハブを収容し、係合フック２１と被係合部３１を係合させた際に、収容された針の逸脱を阻止するためにハブと接触する突起であり、ハブとの接触部位を円筒状のハブ形状に合わせて窪ませている。本例では下部材３の内壁がなだらかに傾斜しているので、ハブ固定手段２３が小さな形状であっても、十分にハブを固定することができる。ここで、下部材３が傾斜していない場合にはハブ固定手段２３の形状をもっと大きく形成すればよく、このように形成しても係合フック２１と被係合部３１の非係合時にチューブを圧迫してしまうことがなければ特に問題はない。また、針が逸脱して手指を傷つけてしまう虞がなければ、特にこのハブ固定手段２３は設けなくてもよい。
【０００９】
下部材３には、先端側に左右一対の被係合部３１が設けられるとともに、この被係合部３１より基端側には収容空間３２が設けられている。
被係合部３１は、上部材２の係合フック２１と係合するように両側から削り取られた左右一対の切り欠きである。尚、本例の形状の他、孔なども採用できる。下部材３の内壁には段差が形成されており、この段差を境界として、先端側が相対的に高くなっている。そして、この段差より基端側には一対の側壁３３が立設されており、この側壁３３で囲まれた空間が針及びハブの収容空間３２になっている。翼が翼状針用クランプの奧まで導入されると、針及びハブがこの収容空間３２に落ちて収容される。また、側壁３３にスリット３４を設けてこれが撓むようにし、翼を導入しやすくしてもよい。
【００１０】
尚、上部材２及び下部材３の先端は、翼を導入し易くするために丸く形成されている。
また、本発明の翼状針においては、一旦、針及びハブを収容して上部材と下部材を係合させたら係合が解除できなくなるような機構を設けてもよい。
【００１１】
次に、図１に示す翼状針用クランプの使用について、図２から図５に基づいて説明する。
図２に示すように、本発明の翼状針用クランプは、係合フック２１と被係合部３１の非係合状態で、翼状針４のチューブ４４上に配置される。
まず、翼状針４の針４１を人体の皮膚組織へ穿刺し、チューブ４４内全体に血液を満たした後、図３に示すように翼状針用クランプの係合フック２１と被係合部３１を係合させる。この時、チューブ４４は押圧部２２によって圧迫され閉塞する。
次に、チューブ４４に血液回路（図示しない）を接続し、係合フック２１と被係合部３１の係合を解除して、血液透析を行う。
血液透析終了後、針４１を人体の皮膚組織から抜去するとともにチューブ４４から血液回路を取り外す。
最後に、図４に示すように、翼状針用クランプに翼状針４の翼４３を導入して針４１及びハブ４２が収容空間３２に収容される位置までスライドさせ、図５に示すように係合フック２１と被係合部３１を係合させる。この時、ハブ４２はハブ固定手段２３により固定される。
【００１２】
【発明の効果】
以上述べたように、本発明によれば、プロテクターの機能とクランプの機能を一つの部材で兼ね備えることができるので、シンプルな構成となり、医療従事者にとっても操作上の負担が軽減される。

BACKGROUND OF THE INVENTION
The present invention relates to a clamp disposed and used on a winged needle tube mainly used during hemodialysis.
[0002]
[Prior art]
After use of the medical puncture needle, recapping is performed to protect the cutting edge. During this operation, a medical worker accidentally damages the fingertip and becomes infected with AIDS or hepatitis. Various countermeasures have been taken to deal with this problem. For example, a winged needle can be slidably disposed on the tube (see Japanese Patent No. 2673682), or the needle tube support portion and the protector can be bent. There are known techniques such as connecting at a portion and bending the connecting portion after use to put the protector over a needle tube (see Japanese Patent No. 2813886).
On the other hand, in a winged needle used in hemodialysis, a clamp that temporarily blocks the flow path in the tube is disposed on the tube in order to prevent blood ejection when the blood circuit is connected.
Therefore, the winged needle used in hemodialysis requires two members, a protector and a clamp, to prevent false punctures and prevent blood squirting. It had the disadvantage that the operation was complicated.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a member having both a protector function and a clamp function, that is, a winged needle clamp that does not require a recapping operation.
[0004]
[Means for Solving the Problems]
As a result of intensive studies to achieve the above object, the present inventor has provided a space in which the needle and hub can be accommodated in the upper member or lower member of the clamp so that the needle and hub can be introduced into this space after use. Thus, it was found that a winged needle clamp having a protector function was obtained, and the present invention was achieved.
[0005]
That is, the present invention includes a base-side flexible bending portion having a tube insertion hole, and an upper member and a lower member connected via the bending portion, and the upper member and the lower member are engaged and disengaged on the distal end side. A winged needle clamp that is freely engageable and is configured such that the tube is compressed when the upper member and the lower member are engaged, and at least the wing between the upper member and the lower member when not engaged. And a space for accommodating the needle and the hub in the upper member or the lower member is provided.
Here, it is preferable that the upper member is provided with a pair of left and right engaging hooks, and the lower member is provided with an engaged portion that engages with the engaging hook.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of the present invention. The winged needle clamp of the present invention includes a proximal flexible bending portion 1 having a tube insertion hole 11, and an upper member 2 and a lower member 3 connected via the bending portion 1. 2 and the lower member 3 can be engaged and disengaged freely at the front end side. The tube is pressed when the upper member 2 and the lower member 3 are engaged, and at the time of non-engagement, at least a gap capable of introducing a blade is generated between the upper member 2 and the lower member 3. It has become. The upper member 2 or the lower member 3 is provided with a space that can accommodate the needle and the hub.
[0007]
The bending portion 1 is a flexible member that connects the upper member 2 and the lower member 3. In this example, the bending portion 1, the upper member 2, and the lower member 3 are made of polystyrene, polycarbonate, polypropylene, polyethylene, or the like. It is integrally formed with a synthetic resin. Further, the bending portion 1 has a tube insertion hole 11, and the winged needle clamp of the present invention is used in a state where the tube is inserted into the tube insertion hole 11. In this example, the degree of curvature is curved so that the upper member 2 and the lower member 3 are substantially parallel, but the angle formed by these members may be increased to about 30 degrees. .
[0008]
The upper member 2 is provided with a pair of left and right engagement hooks 21 on the distal end side, and a pressing portion 22 for compressing the tube is accommodated on the proximal end side from the engagement hook 21 and further accommodated on the proximal end side. Hub fixing means 23 for fixing the hub is provided.
The pair of left and right engaging hooks 21 are provided with a gap larger than the outer diameter of the tube so that the tube can be inserted between them, and are hook-shaped so as to engage with an engaged portion 31 of the lower member 3 described later. Is formed. When the engagement hook 21 and the engaged portion 31 are not engaged, a gap capable of introducing at least a blade is generated between them. Further, the engagement hook 21 is inclined from the distal end side toward the proximal end side, and even if the gap generated between the engagement hook 21 and the engaged portion 31 is narrow as in this example, the wing shape Needle wings are easy to introduce. In addition, in order to make it easy to release the engagement state between the engagement hook 21 and the engaged portion 31, a grip portion 24 may be provided on the engagement hook 21.
The pressing portion 22 is for pressing the tube when the engaging hook 21 and the engaged portion 31 are engaged, and has a vertical cross-sectional mountain shape extending in the left and right directions. About this shape, if it is a shape which can compress a tube, it will not specifically limit. If the tube is not compressed when the engagement hook 21 and the engaged portion 31 are not engaged, the engagement hook 21 is provided on the lower member 3 and the pressing portion 22 is provided on the lower member 3. May be.
The hub fixing means 23 accommodates the needle and the hub in the accommodating space 32 of the lower member 3 described later, and prevents the accommodated needle from deviating when the engaging hook 21 and the engaged portion 31 are engaged. For this purpose, the protrusion is in contact with the hub, and the contact portion with the hub is recessed according to a cylindrical hub shape. In this example, since the inner wall of the lower member 3 is gently inclined, the hub can be sufficiently fixed even if the hub fixing means 23 has a small shape. Here, when the lower member 3 is not inclined, the hub fixing means 23 may be formed in a larger shape, and even when formed in this way, when the engagement hook 21 and the engaged portion 31 are not engaged. If there is no pressure on the tube, there is no problem. In addition, the hub fixing means 23 is not particularly required if there is no risk that the needle will deviate and damage the fingers.
[0009]
The lower member 3 is provided with a pair of left and right engaged portions 31 on the distal end side, and an accommodation space 32 on the proximal end side from the engaged portion 31.
The engaged portion 31 is a pair of left and right cutouts scraped from both sides so as to engage with the engagement hook 21 of the upper member 2. In addition to the shape of this example, holes and the like can be employed. A step is formed on the inner wall of the lower member 3, and the tip side is relatively high with this step as a boundary. A pair of side walls 33 are erected on the base end side from the step, and a space surrounded by the side walls 33 is an accommodation space 32 for the needle and the hub. When the wing is introduced to the wing of the winged needle clamp, the needle and the hub fall into the receiving space 32 and are received. In addition, a slit 34 may be provided on the side wall 33 so that it can be bent to facilitate introduction of the wing.
[0010]
Note that the tips of the upper member 2 and the lower member 3 are rounded to facilitate introduction of the wings.
In the winged needle of the present invention, a mechanism may be provided in which once the needle and hub are accommodated and the upper member and the lower member are engaged, the engagement cannot be released.
[0011]
Next, the use of the winged needle clamp shown in FIG. 1 will be described with reference to FIGS.
As shown in FIG. 2, the winged needle clamp of the present invention is disposed on the tube 44 of the winged needle 4 in a state where the engagement hook 21 and the engaged portion 31 are not engaged.
First, the needle 41 of the winged needle 4 is punctured into the skin tissue of the human body, and the entire tube 44 is filled with blood. Then, as shown in FIG. 3, the engaging hook 21 and the engaged portion 31 of the winged needle clamp are connected. Engage. At this time, the tube 44 is compressed and closed by the pressing portion 22.
Next, a blood circuit (not shown) is connected to the tube 44, the engagement between the engagement hook 21 and the engaged portion 31 is released, and hemodialysis is performed.
After the hemodialysis, the needle 41 is removed from the human skin tissue and the blood circuit is removed from the tube 44.
Finally, as shown in FIG. 4, the wing 43 of the winged needle 4 is introduced into the winged needle clamp and slid to the position where the needle 41 and the hub 42 are accommodated in the accommodating space 32, and the engagement as shown in FIG. The mating hook 21 and the engaged portion 31 are engaged. At this time, the hub 42 is fixed by the hub fixing means 23.
